World : World's 1st Hydrogen Engine For Large Ships Cuts C02 Emissions By 95 Pct
OSAKA, Oct 25 (Bernama-Kyodo) -- A Japanese marine engine manufacturer has developed what it says is the world's first hydrogen-fuelled engine for large commercial vessels, capable of cutting carbon dioxide emissions by more than 95 per cent compared with conventional heavy fuel oil engines, Kyodo News reported.
Japan Engine Corp. has developed what it claims is the world's first hydrogen-fueled engine for large commercial ships, boasting a potential to slash carbon dioxide emissions by over 95% compared to traditional heavy fuel oil engines. The innovative engine was revealed in early September and will be installed on a multipurpose vessel being constructed by Onomichi Dockyard Co., with Mitsui O.S.K.
Lines Ltd. set to conduct onboard demonstration tests in April 2028. The engine employs a high-pressure direct injection system to facilitate stable hydrogen combustion and incorporates safety features like double-walled piping for hydrogen supply lines, as hydrogen is known to be highly flammable and prone to leakage. In August, Japan Engine also introduced the world's first complete commercial ammonia-fueled engine.
While both hydrogen and ammonia are seen as promising next-generation fuels for large commercial vessels, there are challenges to overcome, as hydrogen faces high costs and slow adoption, while ammonia is considered toxic and demands strict safety measures. The International Maritime Organization has set a goal of achieving net-zero greenhouse gas emissions by 2050, and the Japanese government is providing support for these initiatives.
